WTE Power Plant Saves 1.3 Million GPD of Water Daily with Tertiary Water Treatment & Recycling

>” […] The Chester facility generates up to 90 megawatts of clean energy from 3,510 tons per day of municipal solid waste. Previously, the plant used 1.3 MGD — or nearly 5 million liters a day — of municipal drinking water in its waste conversion process, costing the company thousands of dollars in daily water purchases.

To reduce facility operating expenses and the consumption of local water resources, Covanta Delaware Valley upgraded the facility by installing GE’s RePAK combination ultrafiltration (UF) and reverse osmosis (RO) system as a tertiary treatment package. The new system enabled the plant to reuse 1.3 MGD of treated discharge water from a nearby municipal wastewater treatment plant for the facility’s cooling tower.

GE installed two RePAK-450 trains, each producing 450 gallons per minute of purified water. As a result, Covanta Delaware Valley has eliminated the need to purchase 1.3 MGD of local drinking water a day, which results in a substantial financial savings in addition to the environmental benefits.

GE’s RePAK equipment was delivered in 2014, with commissioning taking place the same year, making Covanta Delaware Valley the first North American company to deploy GE’s RePAK technology.

Covanta chose a combined water treatment technology approach because the typical organic and dissolved mineral content of the wastewater requires additional treatment to be suitable for use as cooling tower makeup. RO was selected as the technology of choice, and UF was required as the pretreatment solution.

GE’s RePAK combined treatment system reduces the equipment footprint up to 35 percent as compared to separate UF and RO systems. By combining the UF and RO into a common frame with common controls and GE’s single (patent-pending) multi-functional process tank, GE also is able to reduce the capital costs and field installation expenses when compared to the use of separate UF system and RO systems with multiple process and cleaning tanks, the company says.”<

Pioneering Global Atlas for Renewable Energy Goes Online

See on Scoop.itGreen Energy Technologies & Development

The world’s first open-access Global Atlas of renewable energy resources goes live today, announced at the annual general assembly of the International Renewable Energy Agency (IRENA).

Duane Tilden‘s insight:

–  “In the next 10 years we expect a huge rise in the investments in renewable energy. The Global Solar and Wind Atlas will help us make the right decisions,” says Martin Lidegaard, Danish Minister of Climate, Energy and Building, and President of the 3rd session of the IRENA Assembly.

–  Note to Editors

IRENA is mandated by 159 countries and the European Union to promote the sustainable use of all forms of renewable energy, and to serve as the global hub for renewable energy cooperation and information exchange. Formally established in 2011, IRENA is the first major international organization to be headquartered in the Middle East.

The Hydrélio system will be best used in unused stretches of water, such as quarry lakes, irrigation ponds, water treatment plant lagoons and dams, Ciel et Terre said. “This new floating solar power generation concept addresses the problems of land availability and landscape impacts that large-scale land-based solar power generation projects come up against,” it said. “It makes it possible to conserve land that can be put to other uses, and to convert unused stretches of water into spaces dedicated to renewable electricity production. These stretches of water cover substantial areas.”
